METHOD AND MEAN S FOR/ MAKING DOLL Application filed February 24, 1927.Serial No. 170,449.

This invention relates to methods of making dollheads and the like andto a novel form of mold, and has for one of its objects to providespaced means on one of the mold sections for accurately forming eyeopenings through the plastic material constituting the wall of, the dollhead, with relation to the molded facial features of the head wall, asthe mold is closed and the plastic material placed under compression.

Heretofore, it has been the practice in the doll art to mold the headfrom composition material in front and rear sections to be sub sequentlyjoined or connected. After molding,the front section of the doll headwas provided with spaced eye openings therethrough, and the proper shapeof these openings and their relation to each other vertically andhorizontally of the head wall was more or less dependent upon the skillof the individual worker in the art. Such skill was also relied upon inthe reaming of concave seats or sockets in the inner face of the dollhead wall in accurate relation to the respective openings so that theindividual eye members of an oscillatory eye mounting supported upon theimprovements to provide means whereby re:

liance upon mechanical skill in the manufacture of such doll heads maybe'largely dispensed with, and I therefore, propose not' only toproduce-the eye openings through the doll head wall in the moldingthereof, but toalso providein the inner face of said wall the eye memberreceiving sockets each bearing identically the same relationship to 'there-' spective openings. y

Itis also'another 1mportant ob ect of my' 1 invention to provide a'moldstructure for the above purpose having means for producing on the frontwall of the doll head and between the spaced e e openings horizontallyspaced bearing sur aces at opposite. sides of a central perpendicularplane and against which the shaft or axis 0 the eye mounting is adaptedto be rotatably held, thus obviating any tendency of said shaft to tiltor rock about a perpendicular axis. 1

With the above a id.other ob].ects in view, the invention consists inthe improved'mold for doll heads and the like and imtheform',

construction and relative arrangement of its several parts as will'behereinafter more fully described, illustrated in the accompanyingdrawings and subsequently incorporated in the subj oined claims.

In. the drawings, wherein I have shown one simple and satisfactoryembodiment of my present invention, and in which similar referencecharacters designate corresponding parts throughout the several views,.'

Figure 1 is a longitudinal sectional view through the closed moldtakensubstantially on the line 1-1 of Fig. 2;

Figfi2 is a transverse sectional view taken substantially on .the line-2-2 of Fig. 1;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2,

1 Fig. 4 is a fragmentary top plan view of the lower mold section;

Fig. 5 is a fragmentary elevation of the front molded section of a dollhead looking at the inner side thereof, and

Fig. 6 is a horizontal sectional view through the front part of the dollhead as produced by means of my improved mold and showing an eyemounting oscillatably suspended from the head wall.

Referring in detail to the drawings, the mold structure as" herein shownincludes lower and upper sections 5 and 6 respectively, which are preferbly of heavy cast metal. The lower mold section includes asuitableformed base 5f from which the body 7 rises, said body includinga solidsection 8 and a hollow section 9, said latter section at one endhaving a vertically inclined external surface 10 serving as a guide withwhich a, corresponding end surface llonthe upper mold section 6 coactsand directs the latter mold section to its closed position so thatthecomplementary opposed surfaces 12 and 13 of said mold sections whichare very accurately formed'to produce the required internal and externalcontours of the wall of the doll head, will be accurately related toeach other. The plastic compositlon material indicated at 14 with whichthe surface of the body 7 of the lower mold section is first covered 'tothe required thickness before the mold is closed may consist of woodpulp, papier-mach, or other readily moldable composition material. Asthe mold is closed and the interposed layer of composition material isplaced under compression, the excess material is exuded between theedges of the upper mold section 6 and the base of the lower mold section5. The mold is then subjected to heat by any suitable means to evaporatethe moisture content of the composition material and cause the latter toset or harden in the condition of a uniformly homogeneous rigidstructure.

As heretofore noted, it is one of the important purposes of thisinvention to provide means whereby spaced eye openings and an eye memberreceiving socket associated with each of said openings may be providedin the molding operation to thereby assure the accurate relativepositioning of said openings in symmetrical relation to the nose andother molded features of th doll head wall. To this end, I therefore,provide the solid portion-8 of the body structure of the lower moldsection at the proper predetermined points with the transversely spacedvertically extendin c lindrical openings 15 therethroug ach of theseopenings at its upper end is counterbored as at 16 and a counterbore 17is likewise formed at the lower end of each opening. Through each of theopenings 15 a metal post 18 is positioned, the

lower end portion of each post being threaded to receive a nut 19 whichis permanently fixed in the solid body structure 8.

Each of the posts 18 is provided upon its upperend with a cylindricalenlargement 20 fitting within the counterbore 16 and having adome-shaped projection 21 on its upper face provided with alongitudinally projecting I cutting bit 22 of substantially ellipticalshape e form in cross section. The posts '18 may the dome-shapedprojections 21 and the bits 22 relative to the surface of the lower moldsection in accordance with the predetermined wall thickness of the dollhead to be molded.

Between the upper ends of the opening 15,

the body of the lower mold section 5 is formed with a cavity 23 having acentral upstanding rib 24 formed on thebase wall thereof and extendingdiametrically of the cavity 23 in a plane intersecting the axes of theopenings 15. The end face of this rib 24 has spaced plane portionsindicated at 25 separated by a central convex projection 26.

In the use of the mold, the rods18 are ad j usted so that the major axesof the bits 22 are in line with each other and therefore, with r the rib24. I The plastic composition material 14 is then applied overthemolding surfaces of the lower mold section and over the upper ends ofthe posts 18 and the bits 22. The upper mold section 6 is provided withthe two spaced openings 27 therein of elliptical cross sectional formwhich receive the bits 22 when said upper mold section is applied andthe mold closed. The internal end face 11 of this upper mold sectioncontacting with the opposed face 10 of the lower mold section, guidesthe upper mold section as it is forced downwardly under pressure uponthe plastic material. As this material is thus compresed, it is forcedcompactly into the cavity of the head wall and an elliptical shaped.

opening 29 extending through the front part of the head wall andaccurately centered with relation to said socket. The cavity 23 and therib 24 will also produce upon the inner face of the head wall betweenthe sockets 28 an inwardly projecting cylindrical lug 30 bisected by ahorizontal slot 31. The end surfaces 25 and 26 of the rib 24 roduce thespaced bearing seats 32 at the located in eq'ui-distant spacedrelationto 1ts "central perpendicular plane at right angles to said slot.

As seen in Fig. 6 of the drawings, when the shaft or axis 34 of an eyemounting generally indicated at 33 is positioned in the slot 31, it

.will have bearing contact at spaced points in its length upon the seats32. The shaft may be held in such contact upon these spaced seats by asuitable pin indicated at 35 inserted through registering verticalopenings in the two parts of the lug 30 at the rear side of said ase ofthe slot 31 shaft. Before arranging the eye mounting the eye membersindicated at 36 on the opporotated in, the nuts 19 to adjustablyposition to the axis 34, and which axis, by reason oftheaccurateformation of the sockets 28 and openings 29 in the manner aboveexplained is securely held in accurate parallel relation with the majoraxes of saidopenings, an accurate simulation of the movement of the axisabout an axis in perpendicular relation thereto. Thus the possibility ofbinding of I .the eye members against the walls of the e e sockets isprevented. It will therefore, be

evident that by means of my new mold struc-.-.

ture, not only do I eliminate much of the manual labor, heretoforeincident to the manufacture of such doll heads, but I have also assuredthe very highest degree of accuracy 1n the location of the e e openingsand, the eye member receiving soc ets with respect" to the nose andother'molded facial features of the-head.
